The Bosch GXL18V-225B24 18V Combo Kit provides cordless productivity and versatility. It includes two CORE18V batteries – the best-built battery on the planet – and two powerful tools. The IDH182 EC Brushless 1/4 In. and 1/2 In. Socket-Ready Impact Driver takes screwdriver bits and sockets, for an all-in-one tool with driving power – up to 1,650 In.-Lbs. of torque. The HDH183 Hammer Drill/Driver features KickBack Control, which reduces the risk of sudden tool reactions in binding conditions. It is engineered with an all-metal chuck and an EC Brushless motor delivering 663 In.-Lbs. of torque. Each CORE18V 6.3 Ah battery provides 80% more power than the previous-generation batteries, providing performance comparable to competitor batteries that are up to 35% larger. It features CoolPack 2.0 technology for longer battery life, and it is backward and forward compatible with all Bosch 18V tools and chargers. The included Bosch BC1880 18V Fast Charger can charge a spent CORE18V to 80% in 41 minutes.
